The X10 PRO Plug-In Powerflash Security Interface Module allows almost any device to send X10 signals to an X10 receiver module. When the connected device is activated, the Powerflash sends an ON signal to your X10 receiver. When the device is deactivated, the Powerflash sends an OFF signal. You can connect the Powerflash to a third-party security control panel, for example, to trigger an X10 module when the security system is breached. FEATURES: Sends ON/OFF signals to an X10 receiver module. Activated by dry contact or low voltage output. Plugs into a standard power outlet. CONTENTS: X10 PRO Powerflash Module, Installation Guide.
